Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 The utility model provides a cleaning device for a photovoltaic inverter display screen, comprising a workbench 1, a placement groove 5 is provided on the surface of the workbench 1, a push plate 6 is provided on one side of the placement groove 5, a roller brush 14 is provided above the workbench 1, a mounting frame 12 is provided above the roller brush 14, and the mounting frame 12 is arranged in an inverted U shape, one end of the roller brush 14 is fixedly mounted on an inner wall of one side of the mounting frame 12 through a bearing, a motor 13 is provided at the other end of the roller brush 14, an output shaft of the motor 13 is fixedly connected to the other end of the roller brush 14, a base of the motor 13 is fixedly mounted on the outer wall of the other side of the mounting frame 12, a second moving block 11 is fixedly mounted above the mounting frame 12, a moving assembly is provided on the top of the second moving block 11, a driving assembly that enables the moving assembly to move up and down is installed at one end of the moving assembly, a sliding assembly is installed at the other end of the moving assembly, and a pushing assembly is provided on one side of the bottom end of the driving assembly and the sliding assembly.

[0024] When in use, the driving component drives the moving component to move up and down, so that the installation frame 12 and the roller brush 14 fixed thereon can adapt to display screens of different heights, ensuring that the roller brush 14 can wipe close to the surface of the display screen, and the motor 13 drives the roller brush 14 to rotate. The distance between the roller brush 14 and the display screen can be fine-tuned by pushing the component, or the position of the roller brush 14 can be adjusted as needed during the wiping process to ensure that every part of the display screen can be wiped comprehensively and carefully. The roller brush 14 contacts the surface of the display screen through the bristles on its surface, thereby effectively removing dust and stains on the display screen. Since the roller brush 14 can adapt to display screens of different heights and can slide horizontally on the workbench 1, no matter how big the display screen is, the roller brush 14 can wipe it comprehensively and evenly.

[0025] A through slot 17 is provided inside the workbench 1, and the push plate 6 is movably installed inside the through slot 17. A limit rod 16 and a second electric push rod 15 are provided on one side of the inner wall of the through slot 17. One end of the limit rod 16 is fixedly installed on one side of the inner wall of the through slot 17, and the other end of the limit rod 16 is movably inserted into one end of the push plate 6. A push rod positioning slot for placing the second electric push rod 15 is provided on one side of the through slot 17. The base of the second electric push rod 15 is fixedly installed inside the push rod positioning slot, and the piston rod end of the second electric push rod 15 is fixedly connected to one end of the push plate 6. The push plate 6 is pushed by the second electric push rod 15 and fixed by the limit rod 16, so that the push plate 6 can be stably moved and accurately positioned, and the photovoltaic inverter display screen can be fixed in the placement slot 5 regardless of how the size of the photovoltaic inverter display screen changes.

[0026] The moving component includes a first moving block 4, a second threaded rod 403 and a second driving motor 402. A second moving groove 401 is opened inside the first moving block 4. The base of the second driving motor 402 is fixedly installed inside one side of the first moving block 4. The output shaft of the second driving motor 402 is fixedly connected to one end of the second threaded rod 403. The other end of the second threaded rod 403 is fixedly installed on the inner wall of one side of the second moving groove 401 through a bearing. One end of the second moving block 11 is threadedly connected to the second threaded rod 403. The moving component drives the second threaded rod 403 to rotate through the second driving motor 402. Since one end of the second moving block 11 is threadedly connected to the second threaded rod 403, when the second threaded rod 403 rotates, the second moving block 11 will move up and down along the threaded rod, so that the moving component can achieve fast and precise lifting and lowering adjustment to adapt to display screens of different heights.

[0027] The driving assembly includes a first support frame 2, a first driving motor 202 and a first threaded rod 203. The base of the first driving motor 202 is fixedly installed on the top of the first support frame 2. A first movable groove 201 is opened inside the first support frame 2. One end of the first threaded rod 203 passes through the top of the first support frame 2 and is fixedly connected to the output shaft of the first driving motor 202. The other end of the first threaded rod 203 is fixedly installed on the inner wall of the first movable groove 201 through a bearing. One end of the first moving block 4 is threadedly connected to the first threaded rod 203. The first threaded rod 203 is driven to rotate by the first driving motor 202. Since one end of the first moving block 4 is threadedly connected to the first threaded rod 203, the first moving block 4 can move horizontally along the threaded rod. This design enables the cleaning device to slide horizontally on the workbench 1 accurately and efficiently, thereby adapting to display screens of different widths and ensuring that the roller brush 14 can cover the entire width of the display screen.

[0028] The sliding assembly includes a second support frame 3 and a round rod 302. A sliding groove 301 is opened inside the second support frame 3. Both ends of the round rod 302 are fixedly installed on both sides of the inner wall of the sliding groove 301. The other end of the first moving block 4 is slidably installed on the round rod 302. The sliding groove 301 opened inside the second support frame 3 and the round rod 302 fixedly installed on both sides of the inner wall of the sliding groove 301 provide a stable sliding path for the first moving block 4, ensuring the stability and smoothness of the first moving block 4 during horizontal movement.

[0029] One of the pushing components includes a fixed block 7 and a first electric push rod 8, the bottom end of the fixed block 7 is fixedly mounted on the surface corner of the workbench 1, the base of the first electric push rod 8 is fixedly mounted on the side wall of the fixed block 7, the piston rod end of the first electric push rod 8 is fixedly connected to the side wall of the first support frame 2, and the piston rod end of the other first electric push rod 8 is fixedly connected to the side wall of the second support frame 3. The two groups of pushing components move synchronously, and the pushing components are firmly mounted on the workbench 1 through the fixed block 7, thereby ensuring the stability and reliability of the entire structure. At the same time, the two groups of pushing components adopt the same design and configuration, so that they can move synchronously, thereby ensuring the stability and accuracy of the moving components during horizontal movement.

[0030] The bottom ends of the first support frame 2 and the second support frame 3 are both installed with a limiting assembly, which includes a protrusion 9 and a groove 10. The protrusion 9 is fixedly installed on the surface of the workbench 1, and the groove 10 is opened at the bottom ends of the first support frame 2 and the second support frame 3. The groove 10 is slidably connected to the protrusion 9. When the support frame moves into place, the groove 10 is slidably connected to the protrusion 9, thereby ensuring the stable positioning of the support frame on the workbench 1, effectively preventing the support frame from sliding or deflecting during operation, and improving the stability of the entire cleaning device.
